PD Measurement Tool

The Pupillary Distance (PD) is the distance between the centres of your pupils. With this measurement we can ensure
that the optical centres of your lenses are aligned correctly with your pupils to give maximum comfort and
effectiveness.

When you have your eyes tested most opticians will not include your Pupillary Distance(PD) measurement on your
prescription. Some opticians will gladly give you your PD measurement if you ask for it, while others won’t give
you your PD measurement.
At ThinLenses.co.uk, we have developed a tool that allows you to measure your Pupillary Distance(PD) online.
Once you know your Pupillary Distance (PD) you then have the freedom to purchase all your future glasses from
anywhere that you want.

Check out our video that explains how to measure your Pupillary Distance (PD) quickly and accurately using the
ThinLenses PD Measurement tool.
